Calcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water.This property can be useful for displacing ions from solution.For example, phosphate is displaced from solution by calcium:alcium chloride can serve as a source of calcium ions in an aqueous solution, as calcium chloride is soluble in water.
Calcium nitrate is used in set accelerating concrete admixtures. This use with concrete and mortar is based on two effects. The calcium ion accelerates formation of calcium hydroxide and thus precipitation and setting. This effect is used also in cold weather concreting agents as well as some combined plasticizers.The nitrate ion leads to formation of iron hydroxide, whose protective layer reduces corrosion of the concrete reinforcement.he calcium ion accelerates formation of calcium hydroxide and thus precipitation and setting.
